Vehicle: 2023 Rivian R1S Adventure Package

Hey guys, I'm experiencing an issue with my 2023 Rivian R1S. For the past few days, I've been getting an 'Air Suspension Fault' message on the screen, and the ride height seems a bit off, sometimes noticeably lower on one side after parking. It's not consistent, but it's happening more frequently now.

The message usually clears after a restart, but then comes back. I haven't hit any major potholes or done anything unusual. The truck has about 15,000 miles on it. Has anyone with an R1S or R1T encountered this specific fault? What was the cause and fix?

I'm concerned about potential damage if I keep driving it like this. Any advice on what to check or if this is a known issue would be helpful.

ClearTheCode admin answer:

An 'Air Suspension Fault' on your 2023 Rivian R1S is a common concern for vehicles equipped with air suspension systems. This fault can stem from several components within the complex system.

Possible Causes:

  1. Air Leak: The most common cause is a leak in one of the air springs (air bags), air lines, or the air reservoir. A slow leak can cause the suspension to sag on one side or over time, leading the compressor to overwork.
  2. Air Compressor Failure: The air compressor is responsible for maintaining pressure in the system. If it's failing, not building enough pressure, or running constantly, it can trigger a fault. This might be accompanied by unusual noises from the compressor area.
  3. Ride Height Sensor Malfunction: Each corner of the vehicle has a ride height sensor that tells the control module the current suspension level. A faulty sensor can send incorrect readings, leading the system to believe there's a problem, or causing incorrect leveling.
  4. Control Module Issue: The air suspension control module (often part of the vehicle's Body Control Module or a dedicated module) can sometimes develop internal faults or software glitches that trigger false warnings or prevent proper operation.
  5. Wiring or Connector Problems: Damaged wiring or corroded connectors to the compressor, sensors, or air valves can interrupt communication and cause faults.

Recommended Steps:

  1. Visual Inspection: Carefully inspect around each wheel for any visible damage to the air springs or air lines. Listen for any hissing sounds indicative of an air leak, especially after parking.
  2. Observe Behavior: Note if the fault occurs more frequently in certain conditions (e.g., cold weather, after driving over bumps) or if one specific corner consistently sags.
  3. Avoid Heavy Loads/Off-Roading: Until diagnosed, avoid putting heavy loads in the vehicle or engaging in off-road activities that could put additional stress on the compromised suspension.

When to See a Shop:

It's advisable to have this inspected by Rivian Service as soon as possible. While an intermittent fault might seem minor, a failing air suspension can impact vehicle handling, tire wear, and potentially lead to more expensive repairs if ignored. Rivian technicians have specialized diagnostic tools to identify specific fault codes (e.g., C0561 for suspension malfunction or more specific Rivian codes) and perform proper system tests to accurately diagnose and repair the issue.
